How Much Can I Borrow on a Bank Statement Loan?

Short answer: On a bank statement loan, how much you can borrow is set by your qualifying income, not your tax returns. Lenders average 12 to 24 months of deposits, apply an expense ratio (often 50 percent on business accounts), and use that monthly income to size a loan that keeps your debt-to-income ratio under roughly 43 to 50 percent. Most programs go up to 90 percent loan-to-value and loan amounts of $3 million or more, so the real ceiling is usually your income and your down payment, not a hard cap.

The gap between what a self-employed borrower actually earns and what a lender will lend against is almost always about how the income is counted. A bank statement loan exists precisely because tax returns understate self-employed income after write-offs. Below is how the loan amount is built, step by step, with the numbers that move it up or down.

How is income calculated on a bank statement loan?

Qualifying income on a bank statement loan is the average of your deposits over the review period, reduced by an expense ratio. The lender adds up eligible deposits across 12 or 24 months, divides by the number of months to get an average, then multiplies by the share of deposits it treats as income after business costs. On a business account the default expense ratio is usually 50 percent, so half of your average deposits counts as income. On a personal account many lenders count a higher percentage because personal deposits are assumed to be closer to take-home pay.

Here is a simple example. Say your business account shows $600,000 in eligible deposits over 12 months. That averages $50,000 a month. With a 50 percent expense ratio, your qualifying income is $25,000 a month, or $300,000 a year. That $25,000 figure is what the lender plugs into the debt-to-income math that sizes your loan.

What is the expense ratio and how does it change my loan?

The expense ratio is the percentage of gross business deposits the lender assumes goes to running the business before any of it counts as your income. The default is commonly 50 percent, but real ratios range from about 10 percent to 70 percent depending on the type of business, whether you have employees, and whether you run from home or a leased location. A software consultant working from a laptop has a far lower true expense ratio than a restaurant.

This single number has a large effect. Using the example above, dropping the expense ratio from 50 percent to 30 percent raises qualifying income from $25,000 to $35,000 a month, which can lift the loan amount by hundreds of thousands of dollars. That is why many borrowers get a letter from a licensed CPA or enrolled agent certifying a lower actual ratio. A CPA expense ratio letter can unlock a bigger loan when your books show your costs are genuinely below the lender default.

How much can I borrow with a bank statement loan?

Once the lender knows your monthly qualifying income, the loan amount is capped by your debt-to-income ratio, the loan-to-value limit, and the program maximum. Most bank statement programs allow a DTI up to roughly 43 to 50 percent, meaning your total monthly debt payments, including the new mortgage, cannot exceed that share of your qualifying income. The chart below shows how the pieces combine.

To turn income into a rough purchase price, work backward from DTI. With $25,000 in monthly qualifying income and a 45 percent DTI limit, you have about $11,250 a month for all debt. Subtract your existing car loans, credit cards and student loans, and what remains is the budget for the mortgage payment, including taxes and insurance. At current rates that payment supports a loan in the high six figures for most borrowers. Add your down payment on top and you have your price range.

What down payment and credit score do I need?

Most bank statement loans want at least 10 percent down for the strongest files, and 15 to 20 percent is common. A larger down payment lowers the loan-to-value ratio, which widens the pool of lenders willing to approve you and usually improves the rate. Credit score minimums generally start around 620 to 660, and a higher score both raises your maximum LTV and lowers your rate. Because the rate directly changes the monthly payment, it changes how much loan your income can carry. If your score is holding you back, it is worth understanding what is pulling your score down before you lock an application.

Which deposits count toward my income?

Lenders count regular business or personal revenue deposits and exclude anything that is not recurring income. Transfers between your own accounts, loan proceeds, one-time asset sales, tax refunds and large unexplained deposits are typically stripped out before the average is calculated. That is why a clean, well-organized deposit history matters so much: every deposit the underwriter cannot identify is a deposit that does not count. Before you apply, it helps to convert your PDF statements into a spreadsheet so you can see every deposit line, tag the recurring revenue and spot anything that will get questioned. You can convert your bank statements to Excel in a couple of minutes and total the deposits yourself, which is exactly the math the underwriter will run.

How can I increase how much I qualify for?

The three levers that move a bank statement loan amount are the expense ratio, the deposit total, and your down payment. Lowering the expense ratio with a CPA letter raises counted income. Using the account with the strongest, most consistent deposits, and choosing the 12 or 24 month window that shows your business at its best, raises the average. And a larger down payment lowers the LTV so the loan you do request is easier to approve. Cleaning up your statements first pays off on all three, because a lender that can read every deposit cleanly is a lender that counts more of them. The guide to preparing bank statements for a loan walks through organizing the file, and the bank statement loan requirements for self-employed borrowers post covers the documents that go with it.

Where a bank statement loan fits

A bank statement loan is one of several ways a self-employed borrower can qualify without tax returns. If your money is in assets rather than monthly cash flow, an asset depletion loan may size a larger amount. If your CPA can produce clean financials, a P&L loan can count your real expenses instead of a flat assumption. And if you also earn W-2 or 1099 income, it is worth reading how 1099 income compares to W-2 income in the underwriting. It also helps to know how to present bank statements as proof of income before you apply. Whichever program you choose, the loan officer spreads your deposits the same way, so handing them clean, converted statements shortens the path to a number.
